Tana whom it may concem:

Be it known that I, Kenn. Osrnu Sommnan, a subset of the-Kin of Sweden, re-

siding at ew York, N. have invented I certain new and useful Improvements 1n on the-front or rear portlons of an auto- ..1 firstengage if the' automobi o mobile, or both, and which is adapted to an object with which the automobile would otherwise impact, and when functioning in this way to establish a resistance to the automobile movement which will retard or entirel arrest said movement; or be standing to prevent damage. which would otherwise occur from the impact of objects moving against it. as for example other automob'les approaching or hacking into thecar when standing.

' A further object is to provide in such a I devicea flexible eontacting member readily adtpting itself to theconfiguration of the su ace of any object with which it contacts, although, through its connections with other parts of the bumper construction, the device exereisesthe proper retarding efiect upon the vehicle.

Another object is a bum or as set forth, wherein a plurality of cab eimembers parallel with each other, form a composite primary' member thereby providing a large contact surface.

A further object is a bumper of the charactor described wherein electric connections are provided .for the purpose of giving a den or signal or setting the brakes of the m e, or both.

A further object is such a bum er con-j sisting of a plurality of cables of t e charactor described, wherein the cable member, when distorted in any direction fromits normal stra'fiht line position, will offer resistance to rther movement, and will establish'electric contacts for energizing other devices as brake setting means,

sisting prima y of three parts substantially 1n the same plane,

the outermostpart members a third member flexibly ereby declare in-g means b danger signals, etc.

being formed ofa cable or cables; the innermost member being relatively rigid and with spring ends and between these two mounted contacts wit the rela-.- tivel rigid member whenever the primary mem er 1s distorted. Further objects will appear from the drawings and 8 Referring to t drawings: Fig. 1 .is a perspective view of my cable to establish electric bumper applied; to. the front-of the automo-- bile. 1

The primary flexible member in the construction here. illustrated consists of the flexible cables, 1, 2, 3. These are reeved ifications which follow.

about the shoes l, 5, on each end andare er to seat in the U piece efiected on this side by the nut 14 on the said threads 12, at by the thread at 10.

is provided The opposite end-of the cables the head 16 with the U piece in which -is adjustable on the threads '17 and may be locked in any adjusted position bythe 4 nut 18. A connectingrod 11, threads 10 At 21 is sh the cablf and s rin 8:11

' ends at37 to ject, or if the automobile any object move against contact of some or all of and 12, nut 14 and bracket 13 are provided. Thetension in the cables, 1 and 3, is equalized by the U piece 6 pivoting on the socket 8, whereas the tension of e adjustment of the threaded member 17 m the U piece 15. At 19 and 20 is shown the ca les 1, 2, 3, to hold them m'spaced relationat suitable intervals of their length. own 'aspring'member between the rear spring leaf 22. This 22 is mounted with .the rigid me piece 23 by insulation linin '26 between the members 22 and 23. relatively rigid. member 23 has its ends around as shown at 27, 28, formln-g spring arms and forming support for the spring member 21 through the flexible hinge ends.

The ends 27 are preferably coiled on the outside, as at 29, and the ends of the member 21 coiled on the inside, as at 30. A central pivot 31 which may have a bushing su ports the shoe member 4 and is attached by suitable brackets preferably formed integral therewith.

' This shoe member is surface with cable ,the cables 1, 2, 3, respectively, and when thecables are properly positioned within 'these-lgrooves the'keeper plate 36isbolted over t cables to retain them in the grooves. This plate is referably turned inward between the ea les and provided with ball prevent any possibility of the rigid portions of the shoe engaging against an ob ect which may press the cables inward. A second keeper plate 38 is provided at the other end of the shoe so that when the cables are derthe plates 36, 38, they are held at all times in proper spaced relation therewith. At 39, 40, 41 are shown electric contacts on the member 21 and at 43,44, 45 cooperating contacts on the member "22. Circuit connections arethen established as shown diagrammatically at 46 to the member 21, and at 47 to the member 22. The operation is as follows:

If the automobile move against any obbe stationary and the bumper cable member, or if a body falls upon the cable member, the tension in the said member will draw together the shoes 4, 5 and their hinged ends, forcing the member 21 inwards towards the member22 and causing the cooperating plo the central cable an 2 is ualized with that of the cables 1 and r 3 byii eachend of said member,

The energization'of this circuit may be employed for setting the brakes of the automobile, or giving but my present invention is directed to the cable bumper structure above described,,em-
